baseball bat sweet spot physics
The force on the bat can be worked out from the velocity of the center of mass, (CM), and the torques can be worked out from the angular acceleration. The effect of the hands on the centre of percussion is described in American Journal of Physics, , 622-630 (2004). When a very light bat is swing velocity at maximum, it has little power to transfer to the ball. /V 9 0 R The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. dKoL!8Ka#EV,@V!\j8ZFbp6EE<9cn=N6j0nf;(&;QU6bUD')c@\ We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. If a player can maintain the same bat swing speed with a heavier bat, the heavier bat will produce higher batted ball velocity and an increase in distance. Furthermore, the tip is the lightest and least effective part of the bat. /BitsPerComponent 8 /Filter [/ASCII85Decode /LZWDecode ] 1 0 obj /Gamma [1.8 1.8 1.8] on: function(evt, cb) { /R [316 73 572 791 ] << Wood bats hit farther than metal bats, which is the clear distinction between them. If there is a force of 5,000lb on the ball then . The sweet spot of a baseball bat Rod Cross Physics Department, University of Sydney, Sydney 2006, Australia Received 10 November 1997; accepted 22 January 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be dened either in terms of a vibration node or a centre of percussion.In order to determine how each of the sweet spots inuences the ''feel'' of the . What is velocity of bullet in the barrel? Thank you so much for. . Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. Nathan hopes to test the theory of Robert Adair, a Yale University physics professor and baseball guru, who believes the subjective sweet spot sits on the node where the bat's lowest frequency vibrations drop out. When a player has a bad hit and fails to hit the "sweet spot", it causes vibrations which can cause the bat to bend or break. >> Bats and Balls.- 3. The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. R. Cross, Physics of Baseball & Softball, DOI 10.1007/978-1-4419-8113-4 14, c Springer Science+Business . Bamboo bats are the lightest of the three woods, making them great for players who need to swing fast. The direction of the centripetal force is toward the center of the circle followed by the path of the CM. We use the idea that if a body collides with something, then its angular momentum is conserved with respect to the point of impact. Curve Balls Sweet Spot / Corked Bats / Questec-MLB Zone Evaluation. The consent submitted will only be used for data processing originating from this website. A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand. The direction of the centripetal force is toward the center of the circle followed by the path of the CM. They have a hoop vibration mode - alongside the typical bending modes - that extends their sweet spots. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. To squarely hit a fastball, everything has to . /N 19 0 R For that reason, the walls of a hollow bat need to be relatively stiff so they can vibrate at a frequency larger than 1000 Hz. >> That said, composite and metal bats are still used by younger players who are still developing their skills. A bat is essentially a long stick. keywords: COR(Center of percussion), sweet spot, oscillation Edited : 2020/10/11. Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. Swinging a Bat.- 7. /V 18 0 R The flight of a ball through the air depends strongly on how fast it spins, and in what direction it spins. The weight of a bat can be calculated by subtracting the minus number from the length, which in this case is 33 minus -3, equaling 30 ounces. A light bat can help with dry swing training, as it can be more effective and less strenuous. The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. The impact of a bat and a ball is still not properly understood. At some point you will feel almost no vibration when you tap. the location which produces maximum batted ball speed. The film is shown here, taken at 25 frames/sec. Articles may contain affiliate links which enable us to share in the revenue of any purchases made. Mass has no effect on distance, but if you cant generate enough bat speed to overcome mass, you are doing yourself no favors and going backwards. This area is a product of physics, as the sweet spot is located at the center of percussion, which is the point on the bat that produces the least amount of vibration when hit. External forces are the only way to redirect the ball according to the first law of motion. By coupling the flexible bat to the ball via a parametrized fo. The whole mass of the bat is not involved in the collision, unless the collision happens to occur at the centre of mass of the bat. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. My particular research interests are two-fold: the physics of the baseball-bat collision and the flight of the baseball. A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . A ball that would travel 400 feet in "normal" conditions goes: 6 feet farther if the altitude is 1,000 feet higher 4 feet farther if the air is 10 degrees warmer 4 feet farther if the ball is 10 degrees warmer 4 feet farther if the barometer drops 1 inch of mercury 3 1/2 feet farther if the pitcher is . The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion. In this paper, we analyze the effect on the ball-bat model of corking the bat, and investigate the relationship between the sweet spot and different materials. Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. By maintaining the same swing speed with a heavier bat, players can increase bat speed and distance in the same manner. Both papers can be downloaded. The experiment described below would be an ideal project on the physics of baseball, for any high school or University physics student. Licensed under CC BY-SA 2.0, via Flickr Creative Commons. While carbon dioxide gas is invisible, the very cold gas , Turbines produce noise and alter visual aesthetics. /N 24 0 R Share your thoughts with us below! Its center of mass is 52.6 cm from the knob end. /P 4 0 R Baseball physics is based on fluid dynamics. 2. Not hitting the ball with the sweet spot of the bat causes more vibrations, which causes the sting for the batter. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. Aluminum bats are believed to have longer sweet spots than wooden bats. Materials 2' long wooden plank (a 2"x4" plank works well) U bolt Drill Smooth rod along which the U bolt can slide (e.g., shower curtain rod) Rubber mallet Tape measure Baseball bat Procedure Drill a hole through one end of the 2"x4" plank large enough to insert the U bolt. } endobj The first is where the bat feels best in your hands when you hit. By understanding the physics of baseball bats, players can maximize their performance on the field. The answer depends on how fast each bat can be swung. /N 18 0 R These spots are also described in the physics of tennis page. Neither the CoP nor the 'sweet spot' maximises the velocity which the ball gains from the impact.

When a pitch is played, a turbulent stream of air runs behind the ball. Demonstrating the sweet spot of the bat in a talk I gave at Wrigley Field for University of Illinois alumni in 1997. by Jessy Williamson | Mar 29, 2023 | Equipment. Cylinder 2 (500 Hz) Cylinder 3 (200 Hz), Compare sounds here (recorded with a signal generator connected to a speaker). Where is the Sweet Spot on a Baseball Bat? To understand such collisions it is important to first understand the physics of a collision between one ball and another. The ball also generates potential energy through the bat, resulting in a powerful, far-reaching hit. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. Thats the sweet spot. If the bat approaches a ball incident at speed v. Are heavy bats are more powerful than light bats? The diagram below shows the swing of a wood bat filmed from a spot above the batters head. Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. If the bat approaches a ball incident at speed vin then. The player will swing the bat from low to high, with too much bat speed resulting in fly balls. This is similarly done for tennis rackets and baseball bats. If the ball is struck at the sweet spot of the bat, then the batter feels almost no effect at all. Concentration. Balls compress along the same F vs x curve, regardless of the ball speed, although the actual compression curve for a given ball will depend on its stiffness. The faster the hit ball travels, the longer it should travel. 16 0 obj According to Science Daily, human hands are sensitive to vibration frequencies between 200-700 hertz and we experience the most pain when those frequencies are between 600-700 hertz. /V 16 0 R Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. When a batter hits a ball, the bat will rebound from the force of the collision. Experience. Ball Trajectories.- 4. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. That is, a large fraction of the stored elastic energy in the wall is retained as vibrational energy in the bat. Some results for an Easton BK7 aluminum bat are shown below in 13 QuickTime movie files, each about 1 Mb. Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. /R [316 73 572 791 ] A bat is similar to a racquet but there are some obvious differences. /N 12 0 R /R [316 73 572 791 ] A careful analysis of baseball dynamics shows that this special spot is located at the point where an applied force would result in pure rotation of the bat about the handle grip. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. At one point, called the node, the waves always cancel each other out. endobj The impact on a baseball bat is shorter (since the bat and ball are harder or stiffer), about 1 msec. | A high performance bat has a strong trampoline effect and hence a relatively large COR. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. But how does a batter do it? A similar question: The bumper on a pool table is at a height so that the pool ball does not skid when it hits it. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. Theres a certain romance to wooden baseball bats that goes away the second you swing one. The length and weight of a bat is tailored to the size, strength and hitting style of the individual player. Adding to that is the fact that, When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second the impact could mean up to. If the ball didn't bounce at all then COR would be zero. I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. Newton's third law says that for every action there is an equal and opposite reaction. The bat was swung through an axis 143 mm from the knob end. Metal bats have the distinct composition of wood bats and the balance of pop and density that wood bats lack, whereas wood bats fly faster and farther when hit by wood bats. When the ball hits the sweet spot of the bat, the hand-held end of the bat should come to halt without receiving any impulse from the hand. The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. An aluminum bat is much lighter than a wooden bat, increasing its range and allowing it to hit the ball farther. If you drop the weight, you will be able to use the bat with greater control and power. The cookies is used to store the user consent for the cookies in the category "Necessary". Join PopSci+ to read sciences greatest stories. /WhitePoint [0.9505 1 1.089] The sweet spot of a baseball bat is the area on the bat that produces the most powerful and accurate hit when the ball is struck. Choosing the right wood is essential for the proper performance of baseball bats. READ SOMETHING ELSE Table of Contentsshow But what many people dont realize is that the success of each swing of the bat is a direct result of the science behind how a baseball bat works. As discussed earlier, missing the sweet spot can cause vibrations in the bat. , 231-232 (2001). % A pitch produces a turbulent wake of air behind the ball. A simple introduction to the physics of the collision problem is given here. /Length 459 >> Some of the numbers change with actual speed, but the physics doesnt change. Alan Nathan has the world's best Physics of Baseball site at, Another very interesting Physics of Baseball and Softball site is maintained by Dan Russell at, Lloyd Smith at Washington State University has an excellent site on the physics and engineering of softball, at. The length, weight, and shape of the bat also affect its performance, as longer bats tend to have more power, and heavier bats tend to have more control. callback: cb Where on the bat is the ball struck with the greatest speed? /P 14 0 R endobj You can find the sweet spot by gripping the bat handle with one hand in the same place as when youre swinging. Why? This cookie is set by GDPR Cookie Consent plugin. What two factors determine the location of a baseball bat sweet spot? For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. produce and innovate modern day cricket bats. But strong vibrations are generated for impacts near the tip. Physics of Baseball & Softball R. Cross Published 22 February 2011 Physics, Education Preface.- 1. /V 5 0 R So. << forms: { A ball that strikes the bat does not cause it to vibrate at this point. The ball is spinning clockwise before it bounces and hits the granite block with backspin. While the majority of baseball bats are constructed from wood, there are also metal alloy bats available for certain leagues. Hence, there are two vibration nodes in the barrel. endobj Hitting a ball incorrectly can make a wooden bat break due to the grain of the wood. A 28-inch bat should be ideal for anyone weighing 61 pounds or more who has a height of between 61 and 80 pounds. The sweet spot (where you want to hit the ball consistently) is located about 2 in from the end of the barrel to about 6-7 in on an adult bat. << The cookie is used to store the user consent for the cookies in the category "Analytics". Why does hitting a baseball on the sweet spot of a bat result in a better hit than other parts of the bat? When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. If the ball is at rest (when striking a ball off a T ) then. Its moment of inertia about an axis through its center of mass is 0.184 kg.m^2. If you are between the ages of three and nine and weigh less than 60 pounds, you should buy a 28-inch bat if your height is between three and four inches. Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. Its just $1 per month , By /N 21 0 R Other research indicates that the 'sweet spot' lies between the nodes of the lowest 2 vibrations of the bat. The effect of the hands on the centre of percussion is described in American Journal of Physics, 72, 622-630 (2004). A bat that is too light also hampers the development of a solid, level swing. The size and weight of the bat is a matter of personal preference, but it is important to remember that a bat must be approved by the league in order to be used in official games. What is the fluid speed in a fire hose with a 9.00 cm diameter carrying 80.0 l of water per second? 15 0 obj Try this: dangle the bat lightly by its knob, then use a baseball to strike the bat moving from top to bottom. Analytical cookies are used to understand how visitors interact with the website. When you hit the sweet spot, the bat feels the best in your hand. Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. Additionally, a hard material helps to reduce the amount of vibration that travels through the bat and into the players hands, helping them to maintain control over the bat while swinging. where V = bat speed at impact point just before the impact. Hitting on the sweet spot ensures you dont lose any more energy to making vibrations inside the bat. How do you control where to hit a baseball? If the bat is at rest then we can define the ball speed ratio, Bounce Factor = q = (ball exit speed) / (incident ball speed). I have done quite a bit of independent research in both areas. When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second - the impact could mean up to 5,000 lbs of force. Yes, every ounce makes a difference. So, well hit balls are struck at the sweet spot. Baseball bats are an integral part of the game of baseball, and their physics is an important aspect of the sport. A high performance bat has a strong trampoline effect and hence a relatively large COR. throughout the paper. Both the swinging bat and the pitched ball possess kinetic energy, which is generated by the players who swing the bat and throw the ball. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Magnetism is also an important aspect of baseball because bats use magnetite, a magnetic substance found in the body, as a means of internal navigation. The illumination of the ordinaryof why the sky is blue or why the stars shineis not the least important role of physics and physicists. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. Thick walls are also needed to help prevent the walls dinting or cracking. endobj hitting a baseball is either painful or frustrating. A paper on this subject can be downloaded. /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] Last . However. Though all of this means that us amateurs dont want to have batting practice for more than 10 minutes, it does help you train. /V 13 0 R /Height 99 See, the trouble with wood is that it vibrates. gF/(+GaKo$qneLWDrQ#;5\S(\$q'LM9bYJX9N;hHO_e;>`Y"/'J:I~> >> the location where maximum energy is transferred to the ball. The dead spots in the bat will cause a vibration to be sent down through the handle of the bat into the hands, which ultimately causes vibration or a stinging feeling. The bounce factor found from these and some additional impacts is shown below. The horizontal speed at the contact point depends on the rate at which the ball spins, as well as on the horizontal speed of the centre of mass of the ball. Elastic Properties of Balls.- 9. Lighter bats, on the other hand, are better suited for contact hitters who are looking to make contact with the ball and generate less power. /I << (function() { So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. A first guess would be at the tip of the bat since the tip travels the fastest. It is not difficult to swing a bat. /N 13 0 R stream The more general recommendation is that a teams best hitters should be grouped together in the batting order, rather than spread out, as this maximizes the chances of someone being on base when a good hitter comes to bat. /V 10 0 R In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball. 18 0 obj If the vibration frequency is less than about 1000 Hz, the end result is that ball comes off the bat at a lower speed than off a wood bat of the same weight and swing weight. There is no simple physics answer to the heavy/light bat question here. Allow Dan Russell to explain: Any solid structure has vibrational patterns.. 13 0 obj /P 17 0 R By clicking Accept, you consent to the use of ALL the cookies. Hitting the "sweet spot" is something that baseball players strive for. Ball Hysteresis.- 10. Where is the best place on a bat to hit the ball?
